Will I curse to my TV screen when certain characters appear on the scene? Yes. Because it's fun, and because I have superficial opinions sometimes. But I do it after being involved in DEEP conversation about the layers that build every character in the series. And understanding different points of view to agree with one side or the other. I have challenged my mind to follow a belief my values can agree upon.
Anyone, who after watching arcane, hates on or blames any one character, did not understand what they watched.
There isn't any one character who is narratively 'in the wrong'. We get to see so many different perspectives of so many different characters. We get to see what got them to where they are in their life. We got to see what made them who they are. Almost all of them have done horrible things and have made unforgivable mistakes. They're all deeply flawed. But the point is to show that their actions exist in the specific system they live in.
None of those characters would've done what they did if they didn't live in the world that they did. Their lives are influenced by the system and so the way they go about their lives is also influenced. The system is at fault. The effects of the system are at fault. Not the victims.
